This is harder than it looks.
See those rows of crops? On most farms, you need to be able to drive a tractor through them. I don't mean a riding mower, I mean a giant thing that pulls a tool that's working on 5-10 rows at a time doing things like tilling, seeding, fertilizing, harvesting, etc. If there's big metal pillars every row or every other row, that tool can't be used.
Thus, as pictured, those kinds of panels can only be used on a farm that's not using large multi-row agriculture machinery. That means it'll work for small family farms but not the large ag operations where this sort of tech could really kick ass.
What I would really love to see is more solar over commercial parking lots. That means a million little projects instead of a few huge ones, but think about how much surface area that is overall. It's huge.
The key to doing that is twofold- 1. create a few cookie-cutter designs for the frameworks that can be tweaked for individual projects, and 2. remove red tape from their implementation.
It should be possible for a business to buy off the shelf plans for such a thing, have a local engineer tweak them for the project specifics, and then have a local contractor do the installation, and have this happen in under 6 months.
As it stands, building anything above where humans will be involves a nightmare of engineering and insurance and liability, making it cost-prohibitive for most companies. That needs to get easier. I believe every parking lot should have solar above it- that not only will produce a ton of power, but it'll keep the cars cooler in summer.
In the future, it would be cool to see the steel frames facilitate rails that equipment could ride on and work the field beneath. Perhaps it could even be moved by water pressure, since similar equipment in the shape of large scale sprinklers already exists.
This might never come to pass, because indoor farming can produce the same amount of some crops and grains as the equivalent of 40x as much land.
Yeah I think indoor farming / vertical farming is going to be the ultimate answer. Much more efficient in every way, including resource use, water, pesticide, etc.
Not more efficient use of Gravel. Unless the person's government requires water-barriers/floodwalls on fields for some reason. But yeah, indoor is great, I've personally been experimenting with bulbs in rock wool. They don't seem as likely to bloom on the first cycle, but otherwise they've been thriving.
